If all routes are concurrent to SH roads, then what's the point of having this system at all? If that's the case, I'd say scrap it.

Because it was drafted a good year beforehand? Also, nzlsh is a long way off preview status and I can always merge it in when nzlsh is activated if we don't want to highlight that these roads are motorways (or throw into a ocesm grab-bag system with Australian named motorways).

I'm pretty sure that we have other systems entirely concurrent with other systems - cantch is AFAICS (OK, cansk doesn't yet exist).

I'll continued drafting argrn system but there are many unsigned exits in Argentina. I need to check GSV but it has issues in some Argentinan regions. That's why I stopped drafting argrn last year. Once I'll have completed the system, I'll check for unsigned routes and add a system like cannf, eursf or usasf.

On the one hand, I like the idea of having the system so that the major freeways are colored blue (it does look odd if a place with a freeway system doesn't have any blue routes). On the other, it is wholly concurrent, and the distinction of what is and isn't a motorway seems arbitrary to me; I get the sense that it's used more as a legal function and not really meant to be a coherent "system" of routes.

I also like having major freeways colored blue but that's a different point.
